Telecommunications Expert

This quantum optimization pilot by NTT DOCOMO and D-Wave represents a significant breakthrough in mobile network management. The 15% reduction in paging signals during peak times is a substantial improvement, potentially leading to enhanced network capacity and reduced congestion. This could translate to better service quality for customers and cost savings for DOCOMO by optimizing existing infrastructure rather than investing in new hardware.

The ability to process complex network data 40 seconds vs. 27 hours using classical methods is a game-changer for real-time network optimization. As 5G networks continue to expand, this quantum-powered solution could be important in managing the exponential growth in connected devices and data traffic. DOCOMO's plan to deploy this technology across Japan indicates strong confidence in its scalability and potential long-term benefits.

Quantum Computing Analyst

D-Wave's annealing quantum computing solution demonstrates a practical, real-world application of quantum technology in a critical industry. The success of this pilot could accelerate the adoption of quantum computing in telecommunications and other sectors facing complex optimization challenges. The dramatic reduction in processing time (from 27 hours to 40 seconds) showcases the potential of quantum computing to solve problems that are intractable for classical computers.

However, it's important to note that this is a hybrid quantum-classical solution, not a pure quantum system. As quantum hardware continues to advance, we may see even more significant improvements. This project also highlights the importance of developing quantum algorithms tailored to specific industry problems, a trend likely to drive further innovation in the quantum computing space.

Financial Analyst

For D-Wave (NYSE: QBTS), this successful pilot with a major telecom provider like NTT DOCOMO could be a significant catalyst for growth. It demonstrates the commercial viability of their quantum solutions, potentially opening doors to more telco partnerships globally. The planned deployment across DOCOMO's Japanese branch offices suggests a substantial contract value and recurring revenue potential for D-Wave.

For DOCOMO, the 15% reduction in paging signals could lead to substantial cost savings by optimizing existing infrastructure. This efficiency gain might allow DOCOMO to delay or reduce capital expenditures on new base stations, improving their return on invested capital. Moreover, the potential applications in finance, retail and logistics hint at further operational improvements across DOCOMO's business units, which could positively impact their bottom line in the long term.

Project shows reduction in network signal congestion across base stations, with potential for more efficient signal transmission and equipment cost savings

PALO ALTO, Calif. & TOKYO--(BUSINESS WIRE)-- D-Wave Quantum Inc. (NYSE: QBTS) (“D-Wave” or the “Company”), a leader in quantum computing systems, software, and services and the world’s first commercial supplier of quantum computers, and NTT DOCOMO Inc., Japan’s largest mobile phone operator with over 90 million subscriptions, today announced a quantum optimization pilot that resulted in demonstrable mobile network performance improvements. Using D-Wave’s annealing quantum computing solutions, DOCOMO found that it can reduce congestion at base stations by decreasing paging signals during peak calling times by 15%, potentially leading to increased efficiencies and lowered infrastructure costs. The company plans to deploy the hybrid-quantum solution in production across its Japanese branch offices in the coming months.

D-Wave’s hybrid-quantum technology was used to optimize base station tracking areas — which are small geographical regions — that collectively send paging signals and process extensive historical data on device movements between stations. This helps DOCOMO predict future movement patterns and determine the best combination of base stations to re-establish connections as devices move between tracking areas.

The solution’s efficiency was demonstrated in pilot tests for certain areas in Japan (Tokai, Chugoku, Kyushu regions) when compared to classical methods. While a general-purpose solver took 27 hours, D-Wave’s hybrid solver completed the same task in just 40 seconds. The test results showed that quantum optimization led to a 15% reduction in paging signals, allowing approximately 1.2 times more terminals to be connected during periods of high call volume. This expanded bandwidth for base station resources has the potential to greatly reduce congestion, which would help the company maintain quality network traffic flow even during heavy usage. Additional details around this pilot are available in English and Japanese here and here.

“We anticipate that our quantum optimization strategy will further refine network efficiency, allowing us to maintain high-quality service without additional infrastructure investments as network traffic increases,” said Takatoshi Okagawa, director of research and development strategy at NTT DOCOMO. “With D-Wave’s hybrid quantum technology, we aim to set a new standard in the telecommunications industry for operational performance.”

“Telcos are faced with a slew of increasing operational complexities — from 5G implementation to ever-shifting consumer demands — and need novel solutions to maintain a competitive edge,” said Dr. Alan Baratz, CEO of D-Wave. “DOCOMO’s successful pilot sends a clear signal — that today’s quantum technologies are capable of solving telcos’ complex optimization problems, with the potential to elevate customer satisfaction, maintain network performance and mitigate rising infrastructure costs.”

Following its successful pilot, DOCOMO plans to deploy the annealing quantum computing solution into production at branch offices across Japan. The company is also exploring opportunities to apply quantum optimization across its business units including finance, retail, traffic and logistics, and construction.
